Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75140, here are decompositions:
- 7 + 75133 = 75140
- 31 + 75109 = 75140
- 61 + 75079 = 75140
- 103 + 75037 = 75140
- 127 + 75013 = 75140
- 181 + 74959 = 75140
- 199 + 74941 = 75140
- 211 + 74929 = 75140
Showing the first eight; more decompositions exist.
